Read the first 7 Data Analytics & Population Health flashcards as text

  1. Which data visualization type is best suited for showing trends in patient wait times over 12 months?

    Answer: Line chart

    Line charts are optimal for displaying continuous data trends over time, making month-over-month patterns immediately visible.

  2. A care coordinator reviews a panel report showing patients with HbA1c > 9%. This is an example of which population health activity?

    Answer: Registry-based outreach

    Pulling a registry of patients meeting a clinical threshold—like uncontrolled diabetes—supports targeted outreach and proactive management.

  3. What does the term 'data normalization' mean in the context of EHR analytics?

    Answer: Structuring data to reduce redundancy and improve integrity

    Normalization organizes database tables to minimize duplication and ensure data dependencies make logical sense, improving query accuracy.

  4. Which type of study design is most appropriate for evaluating whether an EHR intervention reduced hospital-acquired infections?

    Answer: Before-and-after quasi-experimental study

    A before-and-after (pre-post) design compares outcomes before and after implementation of an intervention in the same population.

  5. In predictive analytics, 'overfitting' occurs when a model:

    Answer: Performs well on training data but poorly on new data

    An overfitted model memorizes training noise rather than learning generalizable patterns, causing poor performance when applied to unseen data.

  6. Which FHIR resource would most commonly be used to retrieve a patient's list of active diagnoses for population analytics?

    Answer: Condition

    The FHIR Condition resource stores clinical diagnoses and problems, making it the primary resource for pulling diagnosis-based population cohorts.

  7. A health system wants to measure preventable hospitalizations related to poor chronic disease management. Which measure set should they use?

    Answer: AHRQ Prevention Quality Indicators (PQIs)

    AHRQ's PQIs are designed specifically to flag hospitalizations that could have been prevented with good ambulatory/chronic disease care.
